Sistema IoT de riego para el cultivo de tomate riñón en la zona del canal de Salcedo

Abstract

In this research work, an automated system for irrigation control and monitoring in tomato greenhouse farming was implemented, addressing the need to optimize water use in agriculture through IoT technology. This project was developed in response to the increasing water scarcity and the aim to improve the productivity of tomato crops in the Zona del Canal of the canton Salcedo. The system uses a server hosted on database MART to manage the developed data, integrating sensors to measure variables such as soil moisture and temperature, along with actuators like solenoid valves that regulate water dosing through a drip irrigation system. Additionally, it includes a Node-RED dashboard for real-time monitoring and automated decision-making. The implementation focused on testing different water doses according to the phenological stage of the tomato plants to optimize growth and quality. Functionality tests of the irrigation system were carried out, achieving uniform water distribution due to effective soil moisture control. Tests conducted in the tomato greenhouse indicated that the system is beneficial, as proper water dosage control prevents diseases related to water deficiency or excess, such as botrytis and root rot. As a result, the plants achieved optimal growth, leading to higher tomato production.
